    Ironic: Don't use token for glance & check for some unset vars

    There is a regression issue in stable/liberty where using a token for
    auth is failing for glance. We don't need to use a token as we already
    have our credentials. So stop using a token to upload to glance.

    We call various commands to set certain variables. Add some checks to
    make sure those variables are set and fail if they are not.
